the box bod CAB-AXLE B01.

Patented J une 30, 1914.

-To all whom it may concern:

Be it known that 1, WILLIAM EDWARD Gmvnn, a citizen of the United States, residing at Lenoir City, in the county of London and State of Tennessee, have invented a new and useful Improvement in CarAxle Boxes, of which the following is a specification, reference being bad to the accompanying drawing.

My improvement relates particularly to car axle boxes containing anti-friction rollers.

The object of the improvement is to provide such a car axle box formed of a small number of simple and durable/parts.

In the accompanying drawings, Figure 1 is a longitudinal, upright section of a car axle box embodyin m improvement; Fig. 2 is a section on t e ine, 2-2, of Fig. '1, looking toward the right; Fig. 3 is a section on the line, 3-3, of Fig. 1, looking toward the left; Fig. 4 is a section on the line, 4-4, of Fig. 1, looking toward the right.

Referring to said drawings,.A is a car axle. This has a short neck, A, next to the body of the axle. Adjoining said neck is another neck, A longer and smaller in diameter than the neck, A. Around the outer end of the neck, A ,'is a flange, A.

B, is the body of the axle box. This is of the usual form, open at its inner end and at its outer end and flat across the top. Above the outer portion of the neck, A, has a groove, 13, to receive the upper e ge of the dust guard, D. Said guard surrounds the neck, A, and has an inward-directed flange, D conforming to the surface of the neck, A. Said guard is divided on a horizontal line cutting the axis of the axle, thus forming an upper section, 1, and a lower section, 2. Said sections are drawn toward each other by two springs, 3, one located at one side and the other at the other side of said guard, and each having section and having its other end secured'to the lower section of the guard by means of books, 4.

A sleeve or housing, C, surrounds the neck A=, its inner end bearing against the dust guard, D. The interior of said sleeve is cylindrical and large enough to make room for anti-frictional rollers, R, between the inner face of said sleeve and the neck, A with the proper engagement between 'box body,

one end secured to the upper said sleeve, neck, and rollers. At the outer end of said sleeve, a wall, 5, extends downward over the outer end of the axle to approximately the middle of the latter. Said wall may be engaged for the insertion and removal of the sleeve, and it also serves as a means for excluding dust from the upper portion of the bearin The top of said shell is of any suita le broadened form adapting it to form a seat to receive the wedge, W, which is similar to the wed e heretofore used in securing the brass o a car axle boll: in! common iilse. In the form 5 own in te rawings, t e up r rtion of said sleeve has a middle, horifontiil portion, 6, an outer horizontal'portion, 7, along each edge, and an oblique portion, 8, between the portions, 7 and 6. The wedge conforms to the faces, 6, and 8 8, it having a middle horizontal portion resting on the face, 6, and slanting portions, 10, resting on the faces, 8, 8. The upper portion, 9, rises between its ends so that the middle of said ortion will bear against the upper wall of the B. Opposite the inner end of the wedge, the sleeve, C, has an upward-directed flan e, 11, against which the inner end of the we g: bears.

en the parts are to be assembled, the box body, B, is raised and the dust guard,

D, glaced around the neck, A", near the mid 1e of the latter. Then the rollers, R, are inserted between said neck and the dust guard, the latter serving as an expansible, band-form retainer for the rollers. The

rollers being thus temporarily held, the

sleeve, C, is now movedrearward around the neck, A and around the series of rollers. \Vhen the inner end of the sleeve bears against the dust guard, the latter slides inward until it entirely leaves the rollers and assumes its normal position on the neck, A From what has been said, it will be seen thatthe dust guard is a temporary retainer of the rollers, its function in this respect being to receive and hold the rollers in place until the sleeve, C, surrounds said rollers sufiicient-ly to retain them. When the dust guard is in its normal position, its upper edge rests in the groove, B. In such position, said guard forms a stop for the inner end of the sleeve, to prevent further inward movement. The wedge, WV, is next inserted and moved backward until its inner end bears against the flange, 11, on the sleeve. Then the engagement between said flange and the rear gaging means, a dust end of the wedge prevents the forward A, and against outward movement by the flange, A.-

I claim as my invention:
